Stability Improvement

Deg. Rate Reduction

Ion Migration: Mobile ions create internal fields, reduced by IL interface
Moisture Ingress: H₂O decomposes perovskite; ILs form hydrophobic barrier
Thermal Decomposition: Organic cation volatility; ILs anchor A-site cations
Phase Segregation: Halide demixing under illumination; ILs passivate grain boundaries
